I am facing a really bad SharePoint Performance since last week. It is noticeable if someone:
- Creates new Subsites (takes ~ 3min.)
- Edits document properties, press save (takes ~ 1min.)
- Edits lists in Quickedit mode and press save (takes ~ 2min.)
- Adding a Content Type to a library:
Things I did so far:
- Checked the Browsers Developer Tools (F12) in Network tab.
- Increased the Distributed Cache Size
- IIS reset
- ULS Viewer log live while creating new sub site
- Developer Dashboard is empty (Usage and Health is running)
- Deleted the recyle bin content (2. level)
Farm has 1 Application Server (32GB RAM, 4 Cores) and 1 Front-end (16GB RAM, 4 Cores) (here is Distributed Cache running).
SQL Server is not installed via Farm Configuration Wizard. Content Database isn't big. (~5GB)
The CPU and RAM usage is not high and also not increasing while creating or editing. I found those failed jobs:
- User Profile Service Application - Feed Cache Repopulation Job
-
Delete Job History
But that can not be the problem, right?
Update:
Last week Kaspersky was installed on all servers. I know, not good, but that's the way it is. I stopped the program, but I has no effect. Is this maybe the problem?
Solution:
I uninstalled the Kaspersky Antivirus Software on all SharePoint Servers. Application, Frontend, Office Web Apps and SQL, rebooted all Servers and now I got my performance back.
Also the Developer Dashboard is now working (It happend to be empty (Usage and Health was running)). Thanks for all your help! Also thanks for the link Waqas Sarwar MCSE provided https://support.microsoft.com/en-us/kb/952167. I'll maybe try that if it has to be installed again.
